The plastic moment capacity of castellated steel beams should be reduced to lower the Mpl beam. Higher Mpl beam will require bigger column section to avoid failure/yielding in the column section. The research aims to analyse the behaviour of beams ductility of castellated steel beams using “dogbones.” The research used four types of test beam to check the influence of “dogbones” that are made of steel beams IWF 150 x 100 x 5 x 7. They are normal castellated steel beam, variation in the length of dogbones, and variation in the deep of dogbones. The results show that the plastic moment capacity of castellated beams is higher than normal beam. It is, therefore, necessary to reduce the plastic moment capacity of castellated steel beam by using “dogbones.” It will maintain ductile behaviour of the steel structure. Concrete was discussed.
